Yes, I have good relationship with my neighboor. This is temporary. And I would like to avoid to change fixed adresses of my devices
As has been mentioned, you can't do it with what you have now. But ethernet to wifi adapters are relatively cheap and will do what you need. Actually these days many of them are just wifi extenders that have an ethernet port in them so you can plug in a wired device, which would work for you. Some will allow you to disable the extender function and just use it as a bridge, but not all of them.
$20 to $30 solution. Here is one that lets you disable the repeater and just use it as a bridge - https://www.amazon.com/dp/B093WZ15FR/?tag=snbforums-20
And another that is a few dollars cheaper - https://www.amazon.com/dp/B07N1WW638/?tag=snbforums-20
This one is only $15 but is a no-name brand. Not sure if it will let you disable the repeater portion but probably does, supports several different modes, even a basic router. https://www.amazon.com/dp/B083MWXY4K/?tag=snbforums-20 or the non gig port version for $10 https://www.amazon.com/dp/B08LDNNH9Y/?tag=snbforums-20
If you absolutely don't want to spend any money on this then you'll need to use repeater mode and change your IPs for now. If you have a good relationship with your neighbor it shouldn't matter if they can see your devices or not.
